AN OPERATING METHODOLOGY FOR DURABILITY AND SERVICE LIFE IN RECOVERY INTERVENTIONS” (SUM 075)

The retrieval and change process of every historical built context, requires, without any doubts, a particular focus on all past memories as regards traditional building techniques and processes. And whereas such memories meet, it is possible to start some experiments of what today is the applying technical luggage related to the construction and building retrieval field. The research concerns a study of the interventions of restoration realized in a sample area, ("Sassi of Matera"), so as to establish an operating methodology with interpretative and implementable rules for the assessment of the concept of durability and service life in recovery interventions, starting from the preliminary phases of recovery intervention. The objective is to formulate implementable technical intervention sheets which are an indispensable means for intervention planning and programming, starting from an initial check based on validation of the choices made by means of on site experiments and laboratory tests that conform to the regulations in force, and from predictions of the useful life of the utilised components, technological and subject compatibility and maintainability of these components. Intervention monitoring and experimental sampling of historical materials will allow to acknowledge faithfully how materials and building techniques must necessarily act as mediators and at the same time it will consider alternative, innovative and more sophisticated techniques as examples, in order to keep a good compatibility between past and present.
